Abstract

The invention discloses a constructing method for a subacute hyperuricemia renal damage mouse model. The method comprises the following steps that yeast cream and oteracil potassium are taken as a molding agent, a molding experiment is constantly carried out on an experiment mouse for multiple days, a subacute hyperuricemia renal damage mouse model is acquired, wherein during the molding experiment process, the yeast cream is given to the experiment mouse every day, and after the yeast cream is given to the experiment mouse in the last day of the molding experiment, the oteracil potassium is given to the experiment mouse; the weight, serum uric acid level, renal function change and renal pathology change of the experiment mouse are observed, and damage of the molding agent to the experiment mouse is analyzed. According to the constructing method, the mouse is taken as a model animal, the yeast cream in which a uric acid precusor substance is added for a long term is adopted, the oteracil potassium as a uricase inhibitor is taken as the molding agent and is used, and the subacute hyperuricemia renal damage mouse model with stable effect is in accordance with clinical features and issuccessfully constructed.

Description

technical field [0001] The invention relates to the technical field of animal models of hyperuricemia, in particular to a method for constructing a mouse model of subacute hyperuricemia with renal damage. Background technique [0002] Hyperuricemia is a type of disease in which the metabolism of purine in the body is abnormal or the function of the kidneys to excrete uric acid is weakened, resulting in excessive production or decreased excretion of uric acid in the body, which in turn leads to a high level of serum uric acid. If the fasting blood uric acid level exceeds 420 μmol / L for men and 360 μmol / L for women on two different days, it is called hyperuricemia, and long-term hyperuricemia often induces kidney damage. The results of investigation and research show that with the improvement of people's living standards, the incidence of hyperuricemia is increasing day by day, and the cases of hyperuricemia renal damage are also increasing. The current drugs for the treatmen...
